SEAMPOOING-IBOT TLE CAP.

Application led September 20, 1988. Serial No. 683,354.

This invention relates to a massage device. v

of that type especially designed for massag- .ing the scalp and comprises a perforated rubbing element adapted for attachment to a bottle or vessel for allowing an ointment to percolate therethrough during the massaging operation.

Heretofore such rubbing or massaging elements have been moulded from rubber or l@ the like -in the form of a cap having internal threads whereby the cap could be screwed upon the neck of a bottle. It required complicated dies to mould such caps, besides the process was laborious and tedious and mitil gated against large scale production.

' It is an object of this invention to overcome the above noted objections by providing a massaging element in the form of a disk and attaching the same to the bottle by 29 means of a removable metal ring or the like; such a massaging element merely requiring a simple die that can be quickly made, and thatsiniplifies the mouldingprocess so that production is greatly increased.

A further and important objectI is to compensate for any swelling action of the rubber disk massaging element, due to the action thereon of the ointment being dispensed, whereby distortion of said disk is minimized.

It is also an objectof thisinvention to -provide for the control of fluid through the massaging element as will later more fully appear.

lt is a further object of this invention to provide such a massaging device which will provide a vacuum effect for absorbing or drawing impurities from the skin or scalp.

With these and other objects in view which will become more apparent'in the t0 following description and disclosures, this invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

1n the accompanying drawings, which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views: @0 Figure 1 is an elevational view of an ointment bottle with my invention applied thereto.

Figure 6 is an enlarged top plan view of the modified form of massaging element.

Figure 7 is a fragmentary sectional view of a further modified form of massaging element.

Figure 8 is a detail sectional View illustrating the operative position of the expansion joint.

Referring to the drawings, which illustrate certain embodiments of this invention, there is shown an ointment bottle 1 having an I external screw-threaded neck 2 upon which a ring or cylindrical member 3 is adapted to be screwed for conning the massage element 4 which is in the form of a rubber disk having an external diameter substantially equal to the internal diameter of the ring. The ring 3 which is preferably made of sheet metal, is provided with an internal marginal flange 5 at its upper end which overlaps the circumferential margin o f the rubber disk and clamps the same tightly upon the top of the bottle.

This massage element is provided witha slightly raised central portion 6 from which a circular series of flexible rubbing teeth 7 project. Within the circular'series of flex ible rubbing teeth extend a plurality of perforated projections 8 of lesser height than the teeth 7, for supplying the ointment from the bottle during the massaging operatlon when the bottle is tilted so as to be substan# tially upside down. It will be noted that the perforations 8", through the projections 8 are restricted at their inner ends and diverge outwardly. Normally these restricted passages are substantially closed so that only a small quantity of ointment will see therethrough. However, when these projections come inv contact with the scalp or skin and are flexed, the restricted passages will be more or less opened and this exing will cause a greater flow of ointment. The circumferential margin of the massage disk 4 beyond the central raised portion is adapted to underlie the ange 5 of the ring as shown in Figure 4, so that an efficient seal is proity thereto. Within the contines of the rib 9 there is a groove 9a for expansion purposes. Certain kinds of ointment will cause a swelling or expansion of rubber. In such a case, the rib 9 will be expanded outwardly against the inner ,surface of the bottle to assist in sealing the liquid therein, as shown in Figure 8. Said groove 9a under such swelling action opens, permitting an additional expansion to the rib 9.

In Figures 5 and 6 there is illustrated a i slight modification of massage disk. It

mainly -diHers from the one justdescribed in the substitution of a flexible or resilient circumferential flange 10 for the iiexible'rub-v bing teeth 7, whereby a form of vacuum cup is formed that tends to draw the impurities from the scalp and at the same time increases the flow of ointment through the supply ducts in the projections or teeth 8. In Fig ure 7, this vacuum massage cup is shown as provided with perforated projections 8a which terminate in vacuum cups at their upper end whereb the flow of ointment therethrough may e accelerated.

In both forms of the massaging disk, the central portion is thicker than the more remote portions whereby the tendencyv to upward expansion of the disks is decreased or overcome so that the flow of ointment i through the apertures 8b will not be affected.

K It will readily be appreciated that the massage disks are of simple construction and can be uickly moulded. The metal'rings can also .e stamped in mass production. In assembling, it is only necessary to insert the massage disks within the rings. They are intended to fit sufliciently tight therein so that they will be frictionally retained.

The massage ointment is adapted to be sold in bottles which are closed by a Ametal cap. A massageisk assembled in ametal ringis intended to accompanyeach bottle. So 1t is only necessary to remove the metal cap from the bottlev and apply the metal ring with the contained massage disk.

I am aware thatl many changes may be made and numerous details ofconstruction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as m invention:

l. The comblnation with an ointment container havin an outlet, of a massa ing device comprising a disk-shaped tlexi le rubber member positioned over said outlet, means for confining said disk over said outlet comprising a cylindricalmember having a flange engaging the margin of said disk, a circular sealing rib upon the inner surface of said diskfor preventing the escape of ointment between said .disk and cylindrical member, and a circular expansion groove disposed interiorly of said rib, wherebyJ to allow for the outward expansion of said sealing ribj under the swelling action of the rubber when exposed to the ointment being dispensed.

2. The combination with an ointment container having an outlet, of a massaging device disposed over said outlet and embodying a flexible circumferential flange adapted to operate as a vacuum cup, and projections disposed within said flan e having olntment supply ducts therethroug 3. The combination with an ointment container having 'an outlet, of a massagin device disposed on'said outlet and embo ying a flexible circumferential flange adapted to 'operate as a vacuum cup, and iexible projections disposed withln said flange having.

ointment 4supply ducts therethrough and formed at their discharge ends into individual vacuum cups.

In testimony whereof I have hereunto subscribed my name.
